Patent number: 12262169Abstract: The present disclosure provides a bone conduction based sound generating lollipop, a processing method and a system thereto. The bone conduction based sound generating lollipop includes a housing, a trigger, a controller and a sound generating component. The sound generating component, the controller and the trigger are integrated in a packaging cavity formed by the housing, and a separate packaging of the sound generating component is eliminated.
